The D-Wave Two quantum computer clocks in no faster than a standard PC, but those already well-known results still leave us scratching our heads over speed testing.
The latest list of most-powerful computers is a bit of same old, same old. But soon, it won't be so easy to get ahead on the Top500 list by plugging in special-purpose accelerator cards.
Tianhe-2, with 3.1 million processor cores and a lot of Chinese-build technology, is the new leader of the twice-yearly list of the world's 500 fastest supercomputers.
In March, the University of Illinois' National Center for Supercomputing Applications unveiled Blue Waters. CNET Road Trip 2013 checked out our new national supercomputer.
Created to monitor the U.S. nuclear weapons stockpile, the IBM supercomputer was the first to break the petaflop barrier.
The University of Illinois' National Center for Supercomputing Applications will use a Cray supercomputer for the National Science Foundation's Blue Waters project. That computer will incorporate AMD's new 16-core processor.
The machine, located at Oak Ridge National Laboratory in Tennessee, bumps the IBM-based Sequoia system down a notch with its performance of 17.59 petaflops per second.
The system is powered by Nvidia GPUs and thought to be one of the two fastest supercomputers in the world. It's capable of making 20,000 trillion calculations each second.
q&a Nvidia has taken its extremely high-performance graphics chips and restyled them for supercomputing. It looks to be a pretty good fit since some of the top supercomputing centers have adopted them.
The Barcelona Supercomputing Center will deploy the first ARM-based CPU/GPU hybrid supercomputer based on Nvidia chips. Nvidia also announces a joint supercomputer deployment with Cray.
